Hi Danny, Are you familiar with Flex/Flash Shared Objects?
A little synopsis regarding using SharedObject with Flex here: http://sujitreddyg.wordpress.com/2008/01/24/shared-objects-in-flex/ When you write that your application has a "large volume of data", how large? With SharedObject the default storage size is 100KB. Setting storage to "unlimited" is easily accomplished on a user-by-user basis through the Flash Player settings box. The following technote covers "How to manage Local Shared Objects": http://kb.adobe.com/selfservice/viewContent.do?externalId=52697ee8 To really simplify the coding of data synchronization in Flex the key is using LiveCycle Data Services on the backend. Regarding "examples which related to database application", Adobe's Christophe Coenraet's has several examples of a simple Contact Manager application with full downloadable source code. Of late, Christophe's examples have been showcasing synchronization using AIR, but I think that you may be able to adapt them to using Flex in browser with SharedObject for storage. This first post by Christophe mentions that in the early "AIR betas, the Flex Data Management Service uses Local Shared Objects as the local data store. For the AIR 1.0 release, we will use the SQLite database embedded in the AIR runtime instead." http://coenraets.org/blog/2007/10/offline-synchronization-using-air-and-livecycle-data-services/ Christophe's most recent update of this sample app is: InSync: Automatic Offline Data Synchronization in AIR using LCDS 2.6 http://coenraets.org/blog/2008/05/insync-automatic-offline-data-synchronization-in-air-using-lcds-26/ An example not using Flex Data Services, but with just source on using SharedObject with Flex is here: Flex: Using Local Shared Object to store a serialized class instance http://blog.flexmonkeypatches.com/2007/10/11/flex-using-local-shared-object-to-store-a-serialized-class-instance/ Please post back if the above helps? Also please post back regarding what you management finally approves for the project.
